Operations on 2 vector fields
Supposing we have as 2 vector fields:
$F = x^2i + 2zj +3k$

and

$G = r^2e_r + 2\cos\Theta e_{\Theta} + 3\sin(2\phi) e_\phi$

how do i perform the following operations on them?

- $F\cdot r$
- $F\times r$
- |G|
- $G\cdot r$

$r=xi + yj + zk$
if r is positon vector.
with this you can find 1,2 and 4.
